Fix for SELECT with OFFSET

[jozefhornik]

SELECT WITH OFFSET is broken:

<?php
declare(strict_types=1);

include __DIR__.'/../vendor/autoload.php';

$pdo = new \Vimeo\MysqlEngine\Php8\FakePdo('mysql:dbname=depo;host=localhost', 'user', 'password');
$pdo->query('CREATE TABLE `test` (`id` INT NOT NULL) ENGINE=innodb DEFAULT CHARSET=utf8');
$pdo->query('INSERT INTO `test`(`id`) VALUES (1), (2)');

$stmt = $pdo->query('SELECT * FROM `test` LIMIT 10');
var_dump($stmt->fetch());
/*
Correct:
array(2) {
  ["id"]=>
  string(1) "1"
  [0]=>
  string(1) "1"
}
 */


$stmt = $pdo->query('SELECT * FROM `test` LIMIT 10 OFFSET 1');
var_dump($stmt->fetch());
/*
Expected:
array(2) {
  ["id"]=>
  string(1) "2"
  [0]=>
  string(1) "2"
}
Actual:
bool(false)
 */

I added a test and a fix for it.
